Adaptive image denoising using scale and space consistency
(2002) [Journal article]This paper proposes a new method for image denoising with edge preservation, based on image multiresolution decomposition by a redundant wavelet transform. In our approach, edges are implicitly located and preserved in the ... -
Aplicação das transformadas Wavelets em dados de espectroscopia no infravermelho para a determinação de biodiesel e óleo vegetal em blendas biodiesel/óleo vegetal/diesel
(2013) [Journal article]Partial least squares (PLS) calibration models were compared for the determination of biodiesel and vegetable oil in different blends using infrared spectra data (FTIR/ATR). Eighty binary and ternary blends containing ... -
Stochastic texture analysis for measuring sheet formation variability in the industry
(2006) [Journal article]Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced ... -
A wavelet-based approach for analyzing industrial stochastic textures with applications
(2007) [Journal article]Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced ...
